Freeze/Thaw
Tester
The
Schleibinger CDFCIF system is for testing the freeze/thaw resistance
of concrete according to EN 12390-9, RILEM and other standards.
The advantage of this test method is in the very good reproducibility
of the results. With this test procedure, the weathered quantity
of a surface is measured by a number of freeze-thaw cycles. The
test specimens are thereby placed in a solution of sodium chloride
to stress the surface. The result gives an estimate for the resistance
to freeze-thaw cycling for the concrete being tested.
Durability
is, alongside the strength, one of the most important properties
of concrete. It depends on the type of building and the environmental
conditions. Especially in road construction a high resistance to
freeze-thaw cycles is of major importance and is thus one of the
major criteria in testing.
